Typographical machine.



UNITED STATES PATENT OFFICE.

DAVID S. KENNEDY, OF BROOKLYN, NEW YORK, ASSIGNOR TO MERGENTHALER LINOTYPE COMPANY, A CORPORATION OF NEW YORK.

TYPOGRAPHICAL MACHINE.

To all whom it may concern Be it known that I, DAVID S. KENNEDY, a citizen of the United States, and a resident of Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Typographical Machines, of which the following is a specification.

My invention relates to typographical machines, such as linotype machines of the general organization represented in Letters Patent of the United States, No. 436,532, to O. Mergenthaler, wherein circulating matrices are released from a magazine in the order in which their characters are to appear in print and then assembled in line, the composed line transferred to the face of a mold, the mold filled with molten metal to form a slug or 'linotype against the matrices which produce thet ype characters thereon, and the matrices thereafter returned through a distributing mechanism to the magazine from which they started. More particularly, it relates to the means whereby the matrices are conveyed to the distributing mechanism. In machines of this type, the matrices are ordinarily transported to the distributing mechanism by a device known as the second elevator, provided with a toothed bar which engages the correspond ing teeth of the matrices, and from which the latter are moved to a similar stationary 1 bar located in the distributer box, from which in turn they are transferred to the other distributing devices. The elevator bar and distributer box bar are ordinarily formed with beveled or other overlying proj ections, so as to necessitate a relative lateral movement when one is brought into operative relation to the other. The elevator bar is mounted on the elevator so as to be capable of a slight movement with reference thereto, and it often occurs in operation, due to carelessness or the breakage of a part, such as the supporting spring, that the two bars will not be moved into relation to each other in the designed and described manner. Such accidents result in the breakage or mutilation of one or the other of the bars, or of the teeth thereon, or of the corresponding tooth combinations on the matrices themselves. In order that such mishaps may be avoided, I provide the parts with means which guide the elevator bar into proper engagement with the distributor box bar Specification of Letters Patent.

with ease and certainty, and which prevent the excessive relative movement thereof.

In the accompanying drawing, I have shown my invention in preferred form and by way of example, and as applied to a linotype machine of the kind referred to, but obviously many changes and variations may be made therein, and in its mode of application, without departure from the spirit of my invention. For instance, it may be applied to other forms of typographical machines, such as type-setters, type-casters or the like, or machines which handle type or dies instead of matrices. Generally speaking, I desire it to be understood that I do not limit myself to any specific form or embodiment, except in so far as such limitations are speclfied m the claims.

Referring to the drawings: Figure 1 is a rear view of a portion of thedistributing mechanism, etc, having my invention applied thereto; Fig. 2 is a transverse sectional view thereof; Fig. 3 is a similar view, showing the parts in different positlon; and Fig. d is a similar view, illustrating an abnormal operation, such as it is the object of the present invention to prevent.

Referring to Fig. 1, the matrices X are transported to the distributing mechanism by the second elevator, in such manner that the elevator bar A is brought into operative relation to the distributer box bar B, the matrices being then moved from the former to the latter by the transfer device M, when in turn they are lifted individually by the finger C to the other distributing devices (not shown) in the usual way. it will be noted that the grooved bars A and I3 are beveled or chamfered, in such manner that to engage properly, the bar A should move toward the other in a horizontal or substantially horizontal path. The bar A is supported by the link D, pivoted at E to the elevator arm F, and is yieldingly sustained in its uppermost or operative position by the spring G, connected to the link I), and hold ing the latter normally in contact with the pin II on the arm F. So far as described, the parts are or may be of the usual construction, and constitute in themselves no part of my present invention.

It occasionally happens, if the elevator arm F be started suddenly, that the link 1) is given a pendulous or vibratory motion,

bars collide, resulting in the breakage of one or both of them, or ininjury to the ribs thereon, or to the delicate tooth-combina tions of the matrices which engage therewith, or to other connected parts. Such accidents occur not infrequently and cause both expense and interruption to the operation of the machine, It is the purpose of my invention to prevent such mishaps, and

' tot-hat end I have devised the guiding means now to be described. I provide the link D witha guiding element, such as the finger K, (see Figs. 1, 2 and 3), designed tocontact with the extended guiding member J connected to the frame-work of the distributing mechanism. In Fig. 2 the parts are shown at a point just before the bar A. reaches the bar B, at which time the fingerK on the-supportinglink D is in engagement with the stationary guide J. The

A follows a definite arm F continues its movement inthe direc tion of the arrow, and as a result of the guiding contact already mentioned, the bar path, indicated by dotted lines, in a substantially horizontal direction and passes smoothly and easily into operative engagement with the bar B. Fig. 3 shows the parts when the arm F has sub- 5 stantially completed its inward movement,

at which time the bar A has arrived almost in its final position with reference to the bar 13.. In this manner, I insure the correct registration of the two bars and prevent the interference and collisions previously mentioned, which have hitherto resulted in breakage or injury to the parts. I also provide the arm F with a overlying the link D and beyond the pivot E, whereby the bar A and link D will be prevented from dropping, in the event that the spring G is broken or unduly distended. It should also be noted that the pin L is so located, both as to position and distance -With reference to the pin H, that together invention in'preferred form and they constitute the extreme limits of movement necessary for the proper operation of the link D.

As previously stated, I have shown my by way of example, and as applied to the ordinary linotype mechanism, but obviously many variations and modifications thereof, and in its mode of application, will suggest themt selves to those skilled in the art and still be comprised within its scope.

Having thus descrlbed my invention, its construction and mode of operation, What I projecting pin L,

claim and desire to of the United States, is as follows: 7

1. In a typographical machine, a transporter for the type or matrices movable'into operative relation to another part of the machine and comprising a carrier,

porting device proper, andan intermediate member movably connected to the carrier,

and means for maintaining said member in a definite position upon the carrier'so as to" ing type or matrices thereto and comprising the lifting arm, the supporting device proper, and an intermediate link movably connected to the arm and occupying normally a position on the arm such that the supporting device proper will be presented in proper relation to the distributer box, and means to cooperate with said link and restore it to its arm in'the event that-it is displaced therefrom when the elevator is presented to the distributer boxj r Q 3. In atypographical-machine comprising distributing mechanism, the combination of the distributer box'an'd the guide J located in proximity thereto, with the second elevator comprising the 'liftingyarm F, the supporting device A, and the intermediate'link D'movably connected to thearm and occupying normallya position thereon such that the supporting device will be presented in proper relation tothe distributer box, said link being provided with a finger K to cooperate with the guide J so as to insure the proper position of the link on its lifting arm.

4. In a typographical machine, a transporter forthe type or matrices movable into operative relation to another part of the ma-j chine and'comprising a carrier arm, a supporting device proper, an intermediate member pivoted to said arm and movable in opposite directions thereon but occupying normally a position such that the supporting device will be presented in. proper relation to the machine part, and means for limiting the extent of movement of said member" in in combination with means located in proximlty to sald machine part both directions,-

to cooperate with the intermediate member in any position it may occupy within said limits to restore it to its normal position on the carrier arm.

5. In a typographical machine the second elevator comprising the lifting arm F, the matrix bar A, the supporting link D movably connected to the arm F, and the spring secure byIletters Patent a supproper position on thelifting' to do so.

6. In a typographical machine comprising distributing mechanism, the combination of the distributor box and the second elevator for delivering type or matrices thereto and comprising the lifting arm F, the link D pivoted thereto, the supporting device A carried thereby, the spring G to hold the link D normally in such position on the arm F that the supporting device A Will be presented in proper relation to the distributer box, and the pin L to limit the displacement of the link D in the event of accident to the spring.

In testimony whereof I hereunto set my hand this 23rd day of November, 1912, in the presence of two attesting witnesses.
